To all whom 'iilmay concern: Be it known that I, PHILIPPE CHAZAL, a

manufacturer, and a citizen of the French Republic, residing at Lyon,France, have invented certain newand useful lmprovements in theManufacture of Brushes,;of

' which the following isa specification.

This invention relates to improvements in the manufacture of b ushes,and the ob'ect is'to produce such articles having a soli fty hithertounknown by wrapping the tuft or tufts of bristles or the like m aspirally rolled up band of metal or other suitable material views partly.in section showing various forms of application of the invention to a--paint brush. Figs. 6, 7 and 8 are elevations such as pa er, leather,cardboard, independent from t e handle.

In the annexed drawing Figures 1 to 5 are showing the b and to which thebristles are applied before rolling. Fig. 9 is a section on line-9+9 ofFig}; Fig. 10 is asectionon line 10- -10 of 5. Figs. 11 and 12 arecross-sections showing two other forms 'of "the band after rolling orbending and pressure, and Fig. 13 is an elevation of a band 1 anundulating havmg narrower superposed, bandswhich after rolling permit-0fgiving the outer band form to prevent removal of thebristls;

The formation'of the'brushes according to this invention is effectedinthe following manner: I take a band A of thin metal,

ilinen, felt, cardboard or the like which may be com ated, grooved,molded or provided with sma perforations B produced by stampto es ofthe'material ce o the band numerous projections B are formed. This bandAi is then cut out in such a manner as to have an enlargement A at oradjacent one of its ends.

- The bristles or similar material for forming .the brushare spread overthe band A u to the enlargement A which must be left ree, whereupon saidband is rolled upon itself beginning at the narrow end, to which, forthe purpose of giving eater hold to the I gptirator, is fixed a smalmetal stem or tube or instan either by soldering as shown in F1g. 6; b asaw-slit C as in Fig. 7; by a mortise all tenon C C respectively as inFig. 8, or by any other convement means.

The sald stem C being of metal, is adapted to become flattened duringrolling or compression. When such a stem is used it is given a verysmall diameter in order not to form an empty space in the center of thebrush, and the part of said stem which engages the handle A is given aflattened-or angular form as at' C? to prevent rotation thereof, and isrovided with a pointed end C in order to acilitate its enetration intothe wood of a handle. ter rolling, the stem may be either left in thetuft of bristles, or if loosely attached as in Fig. .7, it may beremoved therefrom.

The rollin up of the band A about the stem C may e effected whether thestem'C has been previously secured to a handle or maybe exerted on'theband with a tool of suitable sha e for the purpose of producing therein'ann ling or seriesof grooves for increasing the rigidity of connectionof the bristles (see Figs. 3 and 4). .When the rolling is finished theenlarged part A of the band forms aferrule extending beyond the butts ofthe bristles and the remainder of the band, and adapted to surround the'end of the handle forsecuringthe brush thereto (see Figs. 2, 3, 4 and5). The connection of the handle to said ferrule may be effected in anysuitable or known manner. After having rolled the band, the variouslayers or convolutions thereof are connected together by means of nailsD (Fig. 5), whereupon the' band is compressed in a inold of the form ofa truncated cone.

I may previously insert into that part of the ferrule into which thehandle is to be fixed a solid material adapted to melt at a temperatureabove 100. This material is first melted, then compressed in the'ferrule in which it soon fills any existing interstices. The butts ofthe bristles and convolutions of the band are thus embedded in thismaterial.

It will be understood that it is not necessary that the brushes have acylindrical form as shown in Figs. 9 and 10; but they may be given anoblong, or elongated shape (Fig. 11) by compression in a mold or byother convenient means, or in place of rolling the band, I may fold thesome for example as shown in Fig. 12. Small additional bands A may alsobe placed on the bristles as shown in Fig. 1.3 before the band is rolledup. By this means undulation or corrugation of the bristles is producedwhen the rolling is finished which prevents said said band, a handle,and a lateral snlar' e ment at one end of the band forming a errulewhereby the latter may be attached to the handle substantially asdescribed.

2. A brush comprising a flexible band coiled and compressed to form astock, brush fiber located between the convplutions of said band, acompressible metallic stern attached to the inner end of said band, ahandle, and an enlargement at the other end of said band adapted to forma ferrule for reception of the handle suusta'ii as -2 o describedf 3. Abrush compris a flexible band coiled and compressed to orn'l a' stock,bri1sh 1 fiber located between the 'convolutions of said band, a handle,an enlargement at one 25 end ofthe band adapted tofprrn a fe rrulejor.reception of the handle, nails'*i oni e6 ';together the convolutions oftheuhand an binding material disposed 'infsaid' ferrule.
